UNITED STATES FRANK S. JONES, 0F PHILADELPHIA, PENNSYLVANIA.

METAL-WORKING MACHINE.

Application filed February 13, 1923. Serial No. 618,787.

To all whom it may concern Be it known that I, FRANK S. J ONES, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements inMetal- \Vorking Machines, of which the followingis a specification.

My invention relates to metal working machines, and more particularly tothe general use machine adapted for heavy duty work such as boring,drilling, milling, splining and tapping, oil grooving, rotary planing,slotting and 'the like.

The object of the invention is to provide a machine of the abovecharacter which is lighter, more compact, and occupies less floor space,which may be assembled more conveniently and in which the work is moreconveniently supported.

' These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner,- reference being had tothe accompanying drawings in which Figure 1 is a front elevation of myimproved machine,

. Figure 2 is an end elevation,

Figure 3 is a sectional plan on line 3-3 of Figure 1, y

Figure 4 is an enlarged vertical sectional view taken on the line 4-4 ofFigure 3,

Figure 5 is a vertical-sectional view taken on the line 55 of Figure 4,

Figure 6 is a vertical sectional view taken on the line 6--6 of Figure4, and V Figure 7 is a fragmentary detail sectional view taken on theline 77 of Figure 3.

Briefly my invention includes a bed made in sections adapted to bedetachably connected, a work table slidably mounted on one section, acolumn carrying the spindle and saddle mounted on another section andadapted to slide at right angles to the table, a tail column mounted onanother section at the side of the table opposite the spindle column andadapted to slide at right an les to the table, and means for impartingsli ing movement to the table and columns.

In the drawings, 7, 8 and 9 are bed sections. Sections 7 and 9 arenarrow as compared with the length of section 8. Section 7 is providedwith a flange 10 adapted to be bolted or otherwise detachably secured toone side of section 8 and section 9 is provided with a flange 11 bywhich it may be likewise secured to the opposite side of section 8, the

point of attachment preferably being nearer the rear than the front endof section 8. The

middle section 8 supports the work table 12 which is longitudinallyslidable thereon, section 7 supports the spindle column 13 which isslid-able thereon in a direction at right angles to the path of thetable, and section 9 supports the tail column 14 which is slidablethereon at right angles to the path of the table, the columns being sopositioned that they will slide in alignment with each other.

The tail column may be of any usual con struction. The main column 13carries a saddle 15 which may be of the usual type and which enclosesthe usual gearing. It also supports, in suitable bearings, the usualvertical shaft 16 driven, through suitable gearing, by a motor 17 andserving to drive the poweroperated mechanism. Shaft 16, for the purposesof this invention, is extended through the base of column 13 and aspiral gear 18 is fixed to its lower end. This gear meshes with a spiralgear 19 splined on a horizontal shaft 20 journaled longitudinally of bedsection 7 in brackets 21, 22 and 23. A feed screw 24 is also journaledin these brackets parallel to shaft 20. Bracket 21 is provided with agear box 25 through which the outer ends of shaft 20 and feed screw 24extend, the projecting ends being squared as indicated at 26 to permittheir operation by a 29, projecting outside the box, whereby said gearmay be thrown in or out of mesh with gear 27. Inasmuch as feed screw 24is in threaded engagement with bracket 22 rotation of the screw willcause movement of column 13 longitudinally of bed section 7 and suchmovement may be effected by manual rotation of the feed screw by meansof a crank or by power transmitted from vertical shaft 16, throughspiral gear 18, worm gear 19, horizontal shaft 20 and gears 27 and 28.

The work table 12 is mounted to slide longitudinally upon tracks 30 onbedsection 8, is provided in its upper surface with T- slots 31 forbolting down the work and, in one side, with a dovetail slot 32 forholding index plates or fixtures. A feed screw extending longitudinallyof the table is carried in suitable bearings 34 and 35 on bed section 8and takes through a threaded sleeve 36 carried by a bracket 37 fixed tothe table.

screw 33 and is adapted to mesh with a spiral gear 39 fixed to the endof a shaft 40 journaled in a bearin 41 detachably hung from bed section8 an a bearing 42 mounted on bed section 7 the shaft being in alignmentwith shaft 20. Shafts 20 and 40 are adapted to be connected by a clutch42*, the movable member of the clutch being provided with a lever 43 bywhich tht shafts may be connected or disconnected. The outer end of feedscrew 33 preferably has a squared end 44 adapted to receive a crank bymeans of which the feed screw may be manually actuated. With the membersof clutch 42 connected and gears 27. and 28'out of mesh, feed screws 33may be driven, and the table shifted longitudinally, by powertransmitted from shaft 16, spiral gear 18, spiral gear 19, horizontalshafts 20 and 40 and spiral gears 38.

and 39.

By making the work carrying section comparatively long and disposing theother sections with their len h transverse to the work-supportingsection, I am enabled to provide a suflicient base for the most powerfulmachines and to leave available space which has heretofore been occupiedby the beds. By making the bed in sections, each section carrying one ofthe essential elements, I am enabled to dispense with such machiningwhile being able to assemble the parts in accurate alignment and themachine as a whole is much more readily handled and much better adaptedto shipment. 7 While I have described my invention as taking aparticular form, it will be understood that the various parts of myinvention may be chan ed without departing from the spirit thereo andhence I do not limit myself to the precise construction set forth, but

consider that I am at liberty to make such changes and alterations asfairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. Ageneral use machine including a bed; aspindle-carrying column movable in the direction of the length of thespindle; a work table movable on the bed transversely to the column; afeed screw adapted to move the column; a feed screw adapted to move thetable; a driven shaft, and gearing connecting the shaft and the feedscrews.

1 timer 2. A general use machine including a bed; a spindle-carryingcolumn movable in the di rection of the length of the spindle; a feedscrew adapted to move the column; a gear at the end of the feed screw; apower-driven shaft; a spiral gear thereon; a shaft extending parallel tothe feed screw; a worm gear splined thereon adapted to mesh with thespiral gear, and a gear splined on said shaft and adapted to be engagedwith or disengaged from the gear on the feed screw.

3. A general use machine including a bed; a work table movable on thebed; a feed screw adapted to move the table; a spiral gear fixedon oneend of the screw a spindle-carrying column; a power-driven shaftjournaled in the column; a spiral gear thereon; a horizontal shaft; aworm gear thereon adapted to mesh with'the spiral gear; a shaft inalignment with said horizontal shaft, having a clutch connectiontherewith and carrying a spiral gear adapted to inesh with and drive thespiral gear on the feed screw.

.4 4. A general use machine including a bed made in sections, onesection carrying a work table; a second section carrying the spindlecolumn, and a third section carrying the tail column, the sections beingdetachably connected.

5. A general use machine including a bed made in sections, one sectioncarrying a work table movable longitudinally thereon; a second sectioncarrying a spindle column movable transversely to the path of movementof the table, and a third section carrying a tail column, the sectionsbeing detachably connected.

6. A general use machine including a bed 'made in sections, one sectionbeing adapted to support the work, the other sections carrying,respectively the spindle column and the tail column, the column-suporting sections being narrow coi'npared with the length of the tablesupporting section and disposed with their'length transverse to that ofthe work supporting section.

In testimony whereof name to this specification in the presence of twosubscribing witnesses.
